The solution is to use our qListView web part to display the list instead of OOB list view web part.
The cross-site lookup field gets saved in the siteUrl;#listName;#listItemId format and is displayed correctly in qListView web part using the "Display Field Name" feature under the "If this is a cross..." section (ezEdit->Display Fields->Edit).
The OOB list view web cannot display field value.
